Complement component 5 is a protein that in humans is encoded by the C5 gene.Complement component 5 is involved in the complement system. It is cleaved into C5a and C5b: 1  C5a plays an important role in chemotaxis.2  C5b forms the first part of the complement membrane attack complex.omplement component 5 is the fifth component of complement, which plays an important role in inflammatory and cell killing processes.
The result is the formation of an activated âC1qrsâ, which is an enzyme that cleaves C4 into two fragments C4a and C4b. C4 and C2 activation (generation of C3 convertase) The C4b fragment binds to the membrane and the C4a fragment is released into the microenvironment. Activated âC1qrsâ also cleaves C2 into C2a and C2b. C2a binds to the membrane in association with C4b, and C2b is released into the microenvironment.
